¿Cuántas celdas LSTM debo usar?

¿Existen reglas generales (o reglas reales) relacionadas con la cantidad mínima, máxima y "razonable" de celdas LSTM que debo usar? Específicamente me relaciono con BasicLSTMCell de TensorFlow y la num_unitspropiedad. Suponga que tengo un problema de clasificación definido por: t - number of time...
